Ukrainian drones have attacked three Russian oil refineries as part of a major attack on critical Russian infrastructure. Russian forces said 58 Ukrainian drones were shot down overnight. This comes as the Biden administration has announced it will send a new $300 million weapons package to Ukraine.
Meanwhile, Russian President Vladimir Putin has said in a new interview that Russia is ready to use nuclear weapons if its sovereignty is threatened.

President Vladimir Putin: “From the technical point of view, of course we are ready. The missiles are constantly combat ready. This is firstly. Secondly, and this is accepted by everybody, our nuclear triad is more modern than any other triad. Actually, only us and the Americans have a triad. And we have advanced much more than them. Our triad and the whole nuclear element is more modern.”
